Explanation
The number of port to port fabric connections,
or logins, between the node and a storage controller has decreased.
This might be caused by a problem on the SAN or by a deliberate reconfiguration
of the SAN.
User Response
- Check the error in the cluster event log to identify the object
ID associated with the error.
- Check the availability of the failing device
using the following command line: lscontroller object_ID.
If the command fails with the message "CMMVC6014E The command failed
because the requested object is either unavailable or does not exist," ask
the customer if this device was removed from the system.
- If "yes", mark the error as fixed in the cluster event log
and continue with the repair verification MAP.
- If "no" or if the command lists details of the failing controller,
continue with the next step.
- Check whether the device has regained connectivity.
If it has not, check the cable connection to the remote-device port.
- If all attempts to log in to a remote-device port have failed
and you cannot solve the problem by changing cables, check the condition
of the remote-device port and the condition of the remote device.
- Start a cluster discovery operation by rescanning the Fibre Channel network.
- Check the status of the disk controller. If all disk controllers
show a "good" status, mark the error that you have just repaired
as "fixed". If any disk controllers
do not show "good" status, go to the start MAP. If you return
to this step, contact the support center to resolve the problem with
the disk controller.
- Go to repair verification MAP.
